Many companies are upgrading their wireless networks to 802.11n to achieve greater throughput, wider coverage, and greater reliability, while ensuring the performance of wireless LANs (WLANs) is particularly important to ensure adequate network capacity and coverage. Below, we'll explore how to measure network performance through IPERF, a tool that is easy to use

This tool has been around for a long time in some form or another, some of you old-skool guys may remember a package called Satan, This was the best semi-automatic security analysis tool around back then. From Satan and It's Development came Sara, which is now in It's 3rd generation. Advanced Research's philosophy relies heavily on software re-use. Rather than inventing a new module, Sara is adapted to int

Linux network traffic control tool-Netem Article 1: ConceptsNetem is a network simulation function module provided by Linux 2.6 and later kernel versions. This function module can be used to simulate complex Internet transmission performance in a LAN with good performance, such as low bandwidth, transmission latency, and packet loss. Many released Linux versions

I recently developed an android network packet capture tool. I have searched the internet for a long time. No clue found So we need to work hard on the Linux layer. Therefore, tcpdump in Linux is used to implement the packet capture function. To define tcpdump in a simple way, dump the traffic on a network is a packet analysis

Nethogs, the latest network monitoring tool in CentOS Nethogs is a network traffic monitoring tool on a terminal. It displays the bandwidth usage of each process, so that the network usage can be obtained more intuitively. It supports IPv4 and IPv6 protocols, local NICs, and

When configuring the network, you must specify the path through which the packet is received for the machine. In Linux, a command Route is provided, which can be used to set a static Route for the NIC configured by the ifconfig command. This setting is usually introduced in/etc/rc. d/rc. inet1 during system boot. Here are several examples to illustrate how to use the Route command for Linux network performa

Vnetlib, a powerful Virtual Network Configuration tool under the command line The production of the VMware Server Green Edition has played a major role. To like it, you can find vnetlib.exe In the VMware server‑workstation‑payerdirectory. To create a virtual network adapter use: Start/Wait vnetlib -- add adapter vmnet # To allocate an IP address range use:

the normal upload speed of my 2 m ADSL. At the same time, when I do other things in the uploading, I don't feel the system has any burden, and it is as smooth as it is, this is also commendable! If you do not need to synchronize files on multiple computers, sugarsync is also useful as a file backup tool. At least I think this is a service worthy of my payment, let alone it can be used for free. In addition, the official website also provides a featur
